` SASH ATTACHIVIENT.

Application vled March 16, 1926.' Serial No. 95,131.

It is the purpose of the present invention, to provide, in a sash attachment, means consisting of a hingedl element operatively carried by the upper rail of the lower' sash adjacent one side thereof and provided with a yieldable end portion for engagement with one of the side rails of the upper sash, for preventingr movement of either sash.

Another purpose is to provide means consisting of a base plate for hingedly supporting said element, the base plate being mounted upon the upper rail of the lower sash,

with an extension tongue embedded in. the outer face of the upper rail of the lower sash, in order to obviate binding of the meeting rails of the two sashes.

The invention comprises further features and combination of parts, as will vbe hereinafter set forth, shown in the drawings, and claimed.

In the drawings :a

Figure 1 is a sectional view through the meeting rails of the upper and lower sashes of a window, showing the improved sash attachment as applied, t-he sash engaging hinged element being in position to prevent movement of either sash, and swung inwardly and downwardly in dotted lines.

Figure 2 is a sec-tional view through the meeting rails of the upper and lower sashes of a window, also showing the sash attachment applied.

Figure 3 is a view in elevation of the meeting rails of the upper and lower sashes, showing the application of the sash attachment.

Figure 4 is a detail perspective view of the sash attachment detached from the upper rail of the lower sash.

Referring to the drawings, 1 and 2 designate the meeting rails of upper and lower sashes 3 and 4. The adjacent faces of the rails 1 and 2 are formed as usual to prevent excessive passage of air into the room. VIn other words, the adjacent faces of the meeting rails are beveled, so as to close the space between the meeting rails, caused by the intervening parting strip 5 of the frame.

The sash attachment comprises a base plate 6 and a sash holding element 7. The base plate 6 may be Vconstructed of any suitable metal, either steel or aluminum, or the like, and may be ofl sheet material or cast.

In either case the base plate is relatively broad and is secured to the upper face of the meeting rail 2 by suitable securing means such The holding element 7 is hingedly carried by the base plate. The hinged connection between the base plate and the element comprises a tongue 12 formed integrally with one end of the base plate and the rolls 13 formed integrally with vthe holding element 7. In order to form these rolls 13, the holding element 7 is bifurcated, and the projecting portions of the element caused to be formed by the bifurcation are turned into rolls 13, the bifurcation 14 receiving the tongue 12 (which is turned into a roll 15), there being a hinge pin 16 passing through the rolls 13 and 15, to provide for the hinge connection. The tongue 12 extends inwardly toward the room and upwardly, for the purpose of permitting the holding element to lie laton the base plate, in case the lower sash is in a raised position, in which case the yieldable spring end 17 of the holding element will overlie the extension tongue 9. However, the proper position of the holding element, when the `lower sash is raised, or the upper sash lowered, is as shown in dotted lines in Figure 1. In other' words, the proper position of the holding element is a position inwardly ofV the room and suspended downwarly.

The yieldable or spring end of the holding element is of such curvature that it can engage thel inner face of one of the side rails of the upper sash. In other words, the yieldable terminal or end 17 has a transverse sash engaging straight edge 1S. The terminal end 17 is curved downwardly and inwardly, so that the straight edge 1S is directed toward and in engagement with the side rail of the upper sash in order to bite thereinto, and hence acting to prevent upward movement of the lower sash. or downward movement of the upper sash. Figure 2 shows greater biting action of the straight edge 18 into the side rail of the upper sash than is shown in Figure 1, thereby illustrating secure means for preventing movement of the Sashes particularly Whenthey are n Closed t't'ious opening of the` Windows, butrendevs Y the Windows nosoless n Storms hy preventing rattling.v Y
